The Right Sum

The Right Sum is a brilliant little mental maths game, that really adds some fun to doing mental arithmetic.

is one of our favourite little maths games here at Wordy Puzzle, and is sure to train and hone the mental arithmetic side of your brain in no time at all!

In this game you are given a target sum in blue at the top of each puzzle. You are then given four different numbers below it. Three of these numbers sum together to create the total. However, the fourth is a red herring! What you must do, then, is to work out which three numbers sum to the given total and click those. Just be sure not to click the red herring number, as your game will end there and then!

For instance, if you are given the target of 10 and the numbers are 2,3,5,7 then you will need to click on the 2, 3 and 5 in any order, as 2 + 3 + 5 = 10. However, if you click on the 7 the game will end, as no combination of the four numbers that contains 7 can add up to 10.

And that's all there is to it! For each number you click correctly in each sum you will score a point. And when you complete one sum, another sum will appear, and so on until you either make a mistake or your time of 60 seconds runs out. How will you perform under pressure? It's time to find out!
